Maybe wait a day then sneak in while he's awake and drop a chunk of worm directly in his field of view. Most will snatch it up without thinking. Once he really likes worms he will take them from tongs, BUT not all frogs will feed from tongs. Some just down right dont like them.
this worked a few nights ago but he caught on. last night i offered a cricket with tongs and he very hesitantly and gently took it lol he took 3 more and some worm. thanks again.
